* Simplify function call generation (part 2)Simon Hausmann2012-10-171-1/+1
| | | | | | | | | | | | | | Hide the mapping from function argument to register in a small section of the architecture specific code at the top of the instruction selector and use a generic ArgumentLoader helper class to first try loading function parameters in registers and then fall back to the stack. This is only tested on amd64 right now where we don't end up using the stack right now, so it will need testing/tweaking for ia32/arm.

| | | | | | | The old functions that implement the old calling convention are unused now. Change-Id: I8a6ba76c0ba2442f48a0dc331196ef399a902da0 Reviewed-by: Lars Knoll <lars.knoll@digia.com>
* Directly store constants as immediate Value'sLars Knoll2012-10-171-6/+12
| | | | | | | | | | | This removes a link from the JIT code to the IR, and should improve performance as we need slightly less copies. On 64 bit, Values are stores in 2 instructions instead of 4 now.

* Generate correct code when calling valuesLars Knoll2012-10-171-1/+1
| | | | | | | | | __qmljs_call_value was still using a pointer to a Value. In addition, qcv4isel_masm.cpp was using a wrong order of the arguments. Change-Id: I0414aa732ae8074420e4f11525f5b04712cc1bab Reviewed-by: Simon Hausmann <simon.hausmann@digia.com>
